The recruitment process for the Unsullied kills 2/3 of the people that sign up for it. However, the ones that are left are some of the greatest warriors in the realms. This month, House Targaryen Commanders will be able to add the Unsullied Pikemen to their ranks in the A Song of Ice and Fire: Tabletop Miniatures Game.
From the article:
In the slaver city of Astapor, one of the mightiest military orders is housed. They are the Unsullied. These eunuch warriors are some of the most elite fighters on either side of the narrow sea. Only one in three recruits survive the training process. However, those that make it through gain unparalleled skill in combat. Though they eschew some of the heavier armor of similar units from Westeros, their prowess with all manner of melee weapons makes them a deadly foe. In this article, we take a look at the upcoming Unsullied Pikemen unit box and just what they will bring to the table for House Targaryen commanders.
